Coherent Integration Implementation for China Mobile Multimedia Broadcasting Based Passive Radar with Nonuniform Sampling

The signal structure of China Mobile Multimedia Broadcasting (CMMB) is significantly different from Europe Digital Video Broadcasting-Terrestrial (DVB-T) signal, which implies that the CMMB-based passive bistatic radar faces some new problems in signal processing methods and real-time parallel computation. In accordance with the signal structure of CMMB, this paper proposes a coherent integration method based on nonuniform sampling which is inherently easy to be implemented parallelly. The internal mechanism and processing procedure are clarified first. Then its resolution and sidelobe performance are demonstrated. Finally, real-life data processing confirms the effectiveness of the proposed method.
